GATE.

Application filed June 15, 1925, Serialy No.' 37,282, and in'Canada'irune 8, 1925.

This invention relates toy improvements'in gates,particularlycollapsible gates, Which may be operatedfrom these'at of avehicle avoiding the necessity of dismounting there-- from. v

Further Y objects" aref to provide aA gate of simpleVIA and durableconstruction and easilyV operable.

With-'this and other objects iny view, the invention consistsessentially ofthe combina# tion andiarrangement of par-ts 'hereinaftermore fully described in the accompanying 'spfeccation and'dravvings, inwhich :y

Referring rnowV tothe drawings,I A indi#v cates the gate asa wholeiaiidcomprises prin# cipally l posts* B and@ adjacent onefanother with thegate-operating mechanism D mount ed' therebetween. E indicates a singlepost placedl at a suitable 'distance' froml theposts B' and' C andconnected thereto by the-gateforming chainl 10, thee'nds 11 of' which,are connected' in any well-known manner to` the post EL Mounted on,ktheinside 'of the posts B and; C are U-shaped' guidewaysorchannelmembers 12v in which the gate-operating mechanism D is adapted totravel.` This mechanism comprises an arm 13 pivotally mounted at 14.Secured to and extending frointhe upper extremity of the'1nember`13 arethe links 16 and 17 pivotally mountedat 19 and 2O respectively, the link17 being provided with a latch-operating pin or the like 21and isconnected to a rod 22 to'which'in turn is connected at 23 cables 24 and25. The cables 24'and 25 are adapted to extend over the pulleys 26 and27 suitably mounted adjacent the top of the posts B' and C and extendfrom the posts 'a suitable distance, where they may be convenientlyoperated. The member 13 is suitably bent' at 13a and is provided with apin 18,j another pin 20EL being provided on the link 17, both pins beingdesigned tolimitthe closing movement of the members 13 and 17. v

Pivotally mounted on the arm 13 at 28is aninverte-d U-'shaped member 29lin" which' is supported by the shaftv 30l a sheave`v or groovedA roller311. The upper or lead chain; 32, herelsho'w-n as"- an extension of thegate 10",?'may beseparate therefrom and securedthereto inl any" suitablemanner. This lead chain is designedto travel over the grooved pulley 31and to be suitablyanchored 'atits looseend to'the gate post B as lat"33f1t will also be'noted that the pulley for the lead chain'is arrangedadjacent thereto and preferably thereabove soy that' the leady lchainwill be at an angle' to the top of thegate;

This construction, comprising the lead chain for the top of the gateadapted to'travel'over a movable pulley adjacent to and above the gateandto be anchored securely at its loose end, is'an essential andimportant feature of our invention. The shaft 30 of the sheave 31 isprovided with rollers 36adapt`e'd on the operation of the gatevmechanism tov travel up and down in the guideways 12.'

Directly above the roller 31, as particularly illustratedV in Figure 5,is mounted between the posts B and C the shaft 37. On this shaft is thetrip and lock'mechanism F. The lock member F is provided with a lip oreX- tension 38 which is designed to engage with the lupper extremity ofthe inverted U-,shaped member 29. lllxtendingr rearwardly and slopingdownwardlyfrom the body vportion ofthe locky are the' engaofing hooks39. As illustrated in Figure 1, tnese are adapted to form asubstantially V-shaped slot 40 which permits the upward ordownwardoperation l of the member 17 therebetween. j

In operation, by'a pulll on either loable 24 or 25V the pin 21' engagingthe hook meml bers 39 will cause the lip 38 to become disengaged fromthe member 29. The cable is then released and the gate 10 will by itsown weight' drop to the ground'. as indicated by dot-ted lilies inFigure 1, the sheave 31 travelling downwardly in the guideways 12permitting the chain gate 10 to assume that position; After a vehiclehas passed over the gate on the ground, theother cabler is then' pulledcausing` the .gate-operating mechanism D to be raised, the lip 38engaging the U-shaped member 29 and retaining it in that position. It.should be noted here that as the mechanism for operating thegate isbeing raised, the pin 2l does not engage the hook members 39. Alter thelock F has Vengaged the member 29 and the pull has been released on thecable, the link l? which has in the operative pull been allowed to passfreely over these engaging members, will drop into normal releasingposition as indicated in Figures l and 5; the gate is then closed and ina position to be operated further. y y i As many changes could be madein the above construction and many apparently widely dillerentembodiments of our invention,Y within the scope ot the claims, con*structed without departing from the spirit or scope tliereoii,'itisintended that all matter contained in the accompanying specification anddrawings shall be interpretedv as illustrative and not in a limitingsense.
